  2. Parity (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Parity_(mathematics)

    Even and odd numbers have opposite parities, e.g., 22 (even number) and 13 (odd number) have opposite parities. In particular, the parity of zero is even. [2] Any two consecutive integers have opposite parity. A number (i.e., integer) expressed in the decimal numeral system is even or odd according to whether its last digit is even or odd. That ...

    en.wikipedia.org/wiki/Badminton

    Badminton is a racquet sport played using racquets to hit a shuttlecock across a net.Although it may be played with larger teams, the most common forms of the game are "singles" (with one player per side) and "doubles" (with two players per side).

  4. Burnside problem - Wikipedia

    en.wikipedia.org/wiki/Burnside_problem

    Moreover, the word and conjugacy problems were shown to be effectively solvable in B(m, n) both for the cases of odd and even exponents n. A famous class of counterexamples to the Burnside problem is formed by finitely generated non-cyclic infinite groups in which every nontrivial proper subgroup is a finite cyclic group , the so-called Tarski ...

    Odds and evens may refer to: . Odds and evens (hand game), a two-player guessing game using fingers Odds and evens (patience), a solitaire variant of the card game Royal Cotillion

  6. Even and odd functions - Wikipedia

    en.wikipedia.org/wiki/Even_and_odd_functions

    They are named for the parity of the powers of the power functions which satisfy each condition: the function () = is even if n is an even integer, and it is odd if n is an odd integer. Even functions are those real functions whose graph is self-symmetric with respect to the y -axis, and odd functions are those whose graph is self-symmetric ...

  7. Parity of a permutation - Wikipedia

    en.wikipedia.org/wiki/Parity_of_a_permutation

    The permutation is odd if and only if this factorization contains an odd number of even-length cycles. Another method for determining whether a given permutation is even or odd is to construct the corresponding permutation matrix and compute its determinant. The value of the determinant is the same as the parity of the permutation. Every ...

  8. Science project - Wikipedia

    en.wikipedia.org/wiki/Science_project

    A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.

  9. Even - Wikipedia

    en.wikipedia.org/wiki/Even

    In mathematics, the term even is used in several senses related to odd: even and odd numbers, an integer is even if dividing by two yields an integer; even and odd functions, a function is even if f(−x) = f(x) for all x; even and odd permutations, a permutation of a finite set is even if it is composed of an even number of transpositions
